Abstract

PURPOSE: To improve damping performance by providing a retainer separately for a sealing member which seals the inside and outside of the cylinder of a damper and giving hardness to the end of the substrate of a lip part only in the valve- closing direction, while keeping the part flexible enough in the valve-opening direction.
CONSTITUTION: When a piston rod 10 is thrusted into an inner cylinder 2, oil 12 in the chamber A is given pressure by a piston 19 and the pressurized oil flows into the chamber B through a communication port 15, bending upward the outer peripheral edge of a disc valve 16. On the other hand, the pressurized oil flows also into the reservoir chamber C via a communication port 14, raising the pressure of a gas 13 in the chamber C. By the rise in pressure, the lip part 20b of a valve body 20 is seated on a valve seat 4b so as to prevent the gas 13 from penetrating into the chamber B through the valve chamber D. On the occasion, as the end of the substrate 20c of the lip part 20b is reinforced by a retainer 23, the lip part 20b is prevented from being deformed by bending toward the inside in the radius direction due to the high pressure of the gas.
